Making a new post for my airsoft project, progressing slowly but surely, bit of assembly work this afternoon in the workshop.

As usual I had a change of plan, ditched the burst fire, going for single shot, as I originally intended. Found a sweet piece of pre-drilled 20mm round bar which I opened up to 10mm ID in the drill press, (oh for a lathe)

Bolt open (no hole in barrel yet)



Closed, locking ramp puts pressure on O ring as I want the barrel hole close to the end, the plate fixing bolts are in slots so I can adjust the pressure on the Oring

Do you plan to use this for airsoft games or is it just for hole punching?

Just for fun

This is much more advanced than the single shot airsoft guns my buddies and I made back in the day!

We used to use 100mL syringes with a pipe epoxied to the nozzle and a bunch of rubber bands attached to the plunger to replicate Muskets.
Push an airsoft bb with a wad down the barrel, pull back the plunger and poof!

Made a clamp today for the front section of the gun to secure the barrel to the pvc chamber






M4 thread on top for front sightpost

PVC painted flat black, mostly assembled now, going to mount a small 4x scope I have on it. Connector on the end of the barrel is to attach extension/silencer, about 8" long.

Looks good!

Since you are well versed with high strength metal constriction should consider a move to higher pressures in the 450-850 range using paintball bottles, supersonic airsoft BBs are more than feasible.
